automatic-properties

问题 I have an object with a property implemented like public String Bla {get;set;} After changing the implementation to something like private String _bla; public String Bla { get { return _bla; } set { _bla = value; } } on deserialzation, this Property comes up empty. i have lots of serialized data from the old implementation, and would like to load them with the new implementation is there any way, to change the implentation to be compatible with older binary files? EDIT: Some people might run

问题 Why is it possible to use an object initializer to set a private set auto property, when the initializer is called from within the class which owns the auto property? I have included two class as an example. public class MyClass { public string myName { get; private set; } public string myId { get; set; } public static MyClass GetSampleObject() { MyClass mc = new MyClass { myName = "Whatever", // <- works myId = "1234" }; return mc; } } public class MyOtherClass { public static MyClass

问题 I learned c# recently, so when I learned to write properties, I was taught to do it like this: public string Name { get; set; } Auto properties are great! But now I'm trying to do something a little more complicated, so I need to write a custom pair of accessors. private string _Name; public string Name { get { return _Name; } set { _Name = value } } I know the compiler makes a private instance variable down in it's murky depths when one uses autos, but I'm spoiled and don't want that private

问题 I would like to know if C# automatically implemented properties, like public static T Prop { get; set; } , are thread-safe or not. Thanks! 回答1: It appears not. This is the decompilation with Reflector: private static string Test { [CompilerGenerated] get { return <Test>k__BackingField; } [CompilerGenerated] set { <Test>k__BackingField = value; } } 回答2: Section 10.7.4 of the C# specification states: When a property is specified as an automatically implemented property, a hidden backing field

问题 This question already has answers here : C# 3.0 auto-properties — useful or not? [closed] (18 answers) Closed 2 years ago . When I have Visual Studio 2017 generate properties for me, it will always use the new expression-bodied properties, for example: private static string username; internal static string Username { get => username; set => username = value; } Is there any advantage of using this style over the following or is it just a matter of preference and readability? internal static

The first problem I have is that excel is crashing each time I run this. I am just starting to learn VBA so any help is much apreciated. Thank you! My code is below: Option Explicit Private Sub Worksheet_Calculate() CheckGoalSeek End Sub Private Sub CheckGoalSeek() Range("T7").GoalSeek Goal:=0, ChangingCell:=Range("V7") End Sub 回答1: You appear to be

问题 I was checking the new features of .NET 3.5 and found that in C# 3.0, we can use public class Person { public string FirstName { get; set; } public string LastName { get; set; } } instead of private string name; public string Name { get { return name; } set { name = value; } } If i use the Automatic Properties,what will be the private variable name for Name ? the tutorials on internet says that compiler will automatically create a private variable.So how can i use /access the private variable

问题 I'm using xCode6 Beta 3, and am running into an issue where a code which previously compiled fine (xCode 5.1.1 or xCode6 beta 2) suddenly started to give me "Use of undeclared identifier" errors when accessing an automatically synthesized instance variable: - (void)setFinished:(BOOL)finished { [self willChangeValueForKey:@"isFinished"]; _finished = finished; [self didChangeValueForKey:@"isFinished"]; } //ERROR: Use of undeclared identifier '_finished'; did you mean 'finished'?
